L IQUID FUEL FOB MOTORS.

Io Drawing. Original application filed June 25, 1918, Serial No. 241,755.

' filed Kay 28, 1921.

To all whom/it ma concern:

Be it known tiiat I Aa'rrrun A. BACK- naus,a citizen of the llnited States, resids ing at Baltimore, in the State of Maryland, have invented a certain new and useful Improvement in Liquid Fuels for Motors, of which the followmg is a specification.

My invention relates particularly to fuels designed to be used in aeroplane motors, but is applicable for use in internal combustion motors of all kinds used in.fiying or for other pu es.

The Ob ect of my invention is to provide a fuel which is especially adapted for use in aeroplanes, although it is also applicable for use in internal combustion engines in general.

It is necessary that fuels which are to be used in aeroplane motors shall have great dependability, inasmuch as any uncertainty in the operation of the aeroplane, by reason of variability in the character of the fuel or failure of the fuel to rform its intended work, may bring a ut disastrous" consequences.

For this reason, it is desirable to avoid using insuch fuels large percentages of petroleum products inasmuch as commercial petroleum products do not ordinarily have a constant composition, and are usually comprised of varying quantities of a number of different constituents.

It is, therefore, the object of my invention to provide an aeroplane fuel avoiding these disadvantages and taking into account the circumstances above referred to.

This is a divisional application of my copending application upon motor fue for aeroplanes, Serial Number 241,755, filed June 25, 1918.

Further objects of my invention will appear from the detailed description thereof contained hereinafter.

ile my invention is capable of being carried out in different walys for the purpose of illustration I shal describe only certain ways of car g out the same herein.

For example, a with my invention may be comprised of 40 parts by volume of butyl alcohol, 60 parts by volume of naphtha or gasolene having a specific gravity of from 52 B. to 66 B.

el made in accordance.

Divided and am application Serial No. 473.327.

The percentages of the above constituents may vary to some extent, if desired. For example, the alcohol ma vary from 25% to 50%, although I have 0 tained the best results by the specific composition above given.

The alcohol in the above composition is preferably a highstrength alcohol having a strengti of at least 98%. but I may use an alcohol having even a higher strength, as, for example, an absolute alcohol.

Aeroplane fuels made in the manner described above can be used with the greatest reliability in the operation of aeroplanes, notwithstanding the varied atmospheric conditions to which aeroplane motors are Sm'b'ected.

urthermore, the percentage of light etroleum distillate, that is gasolene or napt a, therein is sufliciently low to prevent the variations in the composition thereof from having any appreciable effect upon the operation of internal combustion engines operated thereby.

Nevertheless, all of these fuels are of such a nature that they may be readily used in internal combustion engines generally. whether used for operating aeroplanes or not.

While I have described my invention above in detail, I wish it to be understood that many chan es may be made therein without departing mm the spirit thereof.

claim:

1. A fuel comprising a petroleum distillate and a butyl alcohol having a strength above 98%.

2. A fuel comprising a petroleum distillate and from 25% to 50% of a butyl alcohol having a strength above 98%.

3. A fuel consisting of 60% of a petroleum distillate and 40% of a high-strength butyl alcohol.

4. A fuel consisting of 60% of naphtha and 40% of a high-strength butyl alcohol.

5. A fuel consisting of 60% of a petroleum distillate and 40% of an absolute butyl alcohol.

6. A fuel consisting of 60% of naphtha and 40% of an absolute butyl alcohol.

7. A fuel com rising a light paraflin hydrocarbon and a igh-strength butyl alcohol from which fuel blending agents are subhydrocarbon and a. butyl alcohol having a stantiall absent. strength above 98%.

Certificate of Correction.

It is hereb certified that in Letters Patent No. 1,474,135, granted November 13, 1923, upon the application of Arthur A. Backhaus, of Baltimore, Maryland, for an improvement in Liquid Fuels for Motors, errors appear in the printed specification requiring correction as follows: Page 1, line 93, claim 3, strike out 60% of, and line 94, strike out 40% and insert instead from 25% to 60%; and that the said Letters Patent should be read with these corrections therein that the same may conform to the record of the case in the Patent Ollioe.
